摘要：

Sulphonated styrene-divinylbenzene copolymers of different structures were heated in vacuum, a nitrogen stream, water, sulphuric acid and benzene. The stability behaviour was studied by differential thermal analysis at temperatures up to 600°C and by isothermal measurements at temperatures between 150°C and 240°C. In aqueous media decomposition of the resins is determined by hydrolysis of the sulphonic acid groups alone; in vacuum, nitrogen stream and benzene, reactions in the polymer backbone under the influence of sulphuric acid and additional crosslinking due to the formation of sulphones have also to be taken into account. © 1979.
